« on: October 29 2014, 10:57:10 PM »I have checked for exhaust leaks way to many times to count when searching for why no boost. No leaks. Wouldnt an exhaust leak tick sound off when bringing up rpms even in park? Load or not, exhaust leak ticking would be there, wouldnt it??
Throw it in gear in the driveway...and foot brake it a tad...should be able to hear the exhaust leak under load.
